The QX50’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Q5 doesn’t offer a lane departure warning system.
The QX50 offers an optional Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Q5 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the QX50 and the Q5 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available all wheel drive, crash mitigating brakes and blind spot warning systems.
The QX50 comes with a full 4 year/60,000 mile basic warranty, which covers the entire truck and includes 24 hour roadside assistance. The Q5’s 4 year/50,000 mile basic warranty expires 10,000 miles sooner.
Infiniti’s powertrain warranty covers the QX50 2 years and 20,000 miles longer than Audi covers the Q5. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Q5 ends after only 4 years or 50,000 miles.
J.D. Power and Associates’ 2016 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Infiniti 12th in initial quality, above the industry average. With 7 more problems per 100 vehicles, Audi is ranked 14th, below the industry average.
The QX50’s 3.7 DOHC V6 produces 105 more horsepower (325 vs. 220) and 9 lbs.-ft. more torque (267 vs. 258) than the Q5 2.0T’s standard 2.0 turbo 4 cyl. The QX50’s 3.7 DOHC V6 produces 53 more horsepower (325 vs. 272) than the Q5 3.0T’s standard 3.0 supercharged V6.
The QX50’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs standard on the Q5 2.0T are solid, not vented.
The QX50’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Q5 2.0T’s standard 60 series tires.
For a smoother ride and more stable handling, the QX50’s wheelbase is 2.9 inches longer than on the Q5 (113.4 inches vs. 110.5 inches).
For better maneuverability, the QX50’s turning circle is .9 feet tighter than the Q5’s (37.2 feet vs. 38.1 feet).
The Infiniti QX50 may be more efficient, handle and accelerate better because it weighs about 250 to 350 pounds less than the Audi Q5.
Pressing a switch automatically raises the QX50’s optional rear seats, to make changing between cargo and passengers easier. The Q5 doesn’t offer automatic folding seats.
The QX50’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Q5 doesn’t offer an easy entry system.
If the front windows are left down on the QX50 the driver can raise them using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Q5 can’t use the remote to operate the windows.
To improve rear visibility by keeping the rear window clear, the QX50 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Q5 only has an intermittent setting, so in a hard rain visibility isn’t as good.
